Until the last two decades, the global perception of how to control our various water bodies was remarkably similar – water management was organised on a sectoral basis, as it always had been. It was only in the 1970s that the people actually responsible for implementing water management began to become aware of the serious implications of such an approach: water quality deterioration, desiccation and an alarming loss of the flora and fauna that characterised their local water environment. It was a growing awareness that led to the formation of the concept of integrated water management, a concept almost universally accepted today as the way forward. However, despite the fact that few dispute the validity of the concept, a number of obstacles remain before this theoretical agreement can be transformed into practical action. Three main bottlenecks stand in the way of implementation: institutional, communicational and socio-political. Whilst solutions to these are available, the key question still to be answered is whether society is really prepared to accept the consequent changes in the way we live that will result from putting the theory of integrated water management into practice. It was this issue that dominated the “Living with water” conference held in Amsterdam in September 1994. The following is a summary of the discussions held there and the various papers that were submitted.

Tianjin City in China is a typical area that suffers from a serious water resource shortage and pollution problems, and this situation has spurred the use of reclaimed water as an additional source of water and an efficient method of improving water quality. This study aims to assess the reclaimed water utilisation amount available and its potential impacts on the water environment and economy, and proposes applicable approaches to establish the optimal development for Tianjin. A water resources-environment-economic management model was constructed, which was accomplished by dynamic linear optimisation. Through scenario analysis, Tianjin's optimal reclaimed water recycle rate can reach 56%, with 475 × 106 tons of reclaimed water amount available (supporting 22% of the water supply), while bringing sufficient environmental and economic benefits, such as reducing 20% of water pollutants and maintaining 6.3% annual economic growth by 2020. This research also suggests that an integrated water management approach is preferable, including a proper introduction of technologies suited to the region's needs, a support system for construction, and control of water pollutant emission sources, especially in agriculture. The originally formulated water management system can be easily applied and extended to solve water issues, especially for water recycling.

Concerns have increased regarding water quality deterioration in arid land water. Water age is a useful indicator of the susceptibility of water bodies to water quality deterioration and is helpful for knowing the basic mechanisms governing the transport of materials through water bodies. In the current study, the spatial distributions of water age in the small lake of Bosten Lake (hereinafter referred to as small lake) were investigated with a two-dimensional hydrodynamic model built on the basis of the Environmental Fluid Dynamics Code (EFDC) model. In particular, the influences of different water flow periods, farmland drainages, and wind directions on water age distributions in the small lake were investigated. The modeled water age in the small lake has high spatial variability. The water age is maximum at the northeastern part and minimum at the center of the small lake. The water age in the small lake is lower during wet periods and gets larger for dry periods. After five years’ simulation, the average water age in the whole small lake system was 594, 684, and 794 days under wet, normal, and dry periods. Increasing the hydraulic connectivity of the small lake can reduce its water age by opening its ecological gate inflow and Ahongkou gate outflow. This is the more favorable hydraulic conditions promoting water exchange in most regions of the small lake and can be used in hydraulic engineering to improve its water age. The farmland drainages should be controlled around the small lake. The mean water age of the whole small lake under the northwestern wind is lower than that under the southwestern wind. The simulated results provide important information for comprehending the water exchange efficiency, help in discovery of areas of the small lake most likely to experience water quality degradation, and can be used to design the engineering projects to improve or protect the water environment.

Nowadays, ecological problems are being caused by economic aspects, and other hand economic issues are arising from ecological and environmental problems. Therefore, it is important to consider both social and economic factors, and take a basin approach to solving environmental problems. To find a relationship between economy and ecology, complex study of river basins is extremely important in establishing conditions for sustainable development in our country. This paper shows the results of applying DPSIR (Driver-Pressure-State-Impact-Response) analysis for Ulaanbaatar city, undertaken as part of a project on Integrated Water Management for the Selenge River Basin. The DPSIR analysis looks at the linkage between the economy and environment for the water quality and water resources of Ulaanbaatar. We used mDSS4 software to evaluate a range of management responses suggested by these issues and found that charging for pollution and measuring water use would have the largest overall impact on water quality and water resources respectively. The analysis was carried out for Ulaanbaatar, because it was identified as one of the key hotspot areas in the Selenge River Basin, which is the main river basin in Mongolia, in terms of both the economy and natural systems.DOI: http://dx.doi.org/10.5564/pmas.v0i4.43Proceedings of the Mongolian Academy of Sciences 2009 No 4 pp.22-31

This paper describes the development and implementation of an Integrated Water Management Strategy for the catchment of the Wilderness Lakes in the Southern Cape, South Africa. The area is a popular tourist destination due to its environmental variety and scenic beauty. The main land uses in the catchment are: agriculture, forestry, tourism, residential settlement and the natural environment. These land uses compete for a share of the available water resources and have different water quality demands, while at the same time each has an impact on the water quality and quantity and also on other land uses. The water management strategy developed for Wilderness aimed at the responsible management and fair distribution of the available water resources (both quantity and quality) and on the sustainable use of these resources, taking full cognisance of the wishes and opinions of all interest groups in the area. The natural environment played a very important role in the development of the strategy and it was found that a more natural management of the estuary mouth would assist in maintaining the natural characteristics of the Wilderness system. The paper also addresses the structures and management body proposed to implement the Water Management Strategy.

Within the scope of the research program of Integrated Water Management Working Group, new research, focused on developing a computer aided system for policy analysis of water management for international river basins, has been launched at Delft University of Technology. This paper refers to conceptual strategies included in creating a part of the computational framework that will be used to support policy analysis of water quality management. Moreover, it outlines major process formulations and process constants referring to modelling the fate of trace metals (Cd, Cu, Zn), PCBs, PAHs, triazines (atrazine, simazine) and pesticides (dichlorovos, mevinphos, lindane). The choice of these substances is tailored to the prevailing water quality concerns that exist in the Meuse basin.

PKM activity is based on the phenomenon of many people who do not get access to drinking water services (SPAM) in standard quality. The PKM Objects is a community in Cikole village Lembang district, Bandung Barat regency whose predominantly work as farmers and use raw water sources to fulfil their needs and even for drinking water direct from the surface water comes from mountain spring water, without the appropriate water treatment standards. The water from the source  accommodated through the water reservoirs and then distributed by gravity directly to each home with simple piping systems, without going through the process of screening and testing the water quality in advance. Regarding quality, the water requires the filtering, especially during the rainy season. Therefore through the PKM activity of "The Training of Environmental Sanitation Management: Water Treatment” hopes that the people, besides the understanding the standard criteria of water quality, are also able to do the water treatment through screening models / simple water purification that can be done independently by the community. The PKM activity has involved several related institutions, starting at the level community such as RT, RW, Kadus, water management, Cikole village officials and Lembang district, Bandung Barat regency.

The book of Jeremiah reflects a particular period in the history of Judah, certain theological perspectives and a particular portrayal of the prophet Jeremiah. Covenant theology played a major role in Jeremiah’s view of life and determined his expectations of leaders and ordinary people. He placed high value on justice and trustworthiness, and people who did not adhere to this would in his view bear the consequences of disobedience to Yahweh’s moral demands and unfaithfulness. The prophet expected those in positions of leadership to adhere to certain ethical obligations as is clear from most of the nouns which appear in Jeremiah 5:1–6. This article argues that crisis situations in history affect leaders’ communication, attitudes and responses. Leaders’ worldviews and ideologies play a definitive role in their responses to crises. Jeremiah’s religious views are reflected in his criticism and demands of people in his society. This is also true as seen from the way the people and leaders in Judah responded to the prophet’s proclamation. Jeremiah 5:1–6 emphasises that knowledge and accountability are expected of leaders at all times, but in particular during unstable political times.
